The RMSEP
was 2.45, that meets the EU requirement (less than 2.5). As a consequence,
the prediction formula (Eq. (2)) to be used for the OGP
equipment was:
Yp ¼ 61:21920−0:77665 X1 þ 0:15239 X2 ð2Þ
where:
Yp predicted lean meat percentage in the carcass
X1 back fat thickness (mm)
X2 muscle thickness (mm).
The average predicted lean meat percentage determined by applying
the prediction formula developed for the OGP equipment is
56.30%, the same as the average reference lean meat percentage
resulting from the dissection experiment (it is 56.97% for females and
55.65% for males).
4.1.2. Prediction formula for the FOM equipment
The method of linear regression was applied for data measured with
the FOM equipment as well. The regression model was statistically
